Abstract

This study presents a novel MCM-41/UiO-66 hybrid nanostructure, achieving exceptional demulsification efficiency and recyclability, offering a sustainable solution for oil-water emulsions in the petroleum industry. With a remarkable 99 % demulsification efficiency and minimal residual oil content, MCM-41/UIO-66 demonstrates exceptional separation capabilities. The successful hybridization of UiO-66, integrating seamlessly with silica-based support, preserved intrinsic structures and enhanced thermal stability. The material exhibits improved textural properties and porosity as well as effective phase separation capabilities, as validated through rigorous testing. Quantitative analysis illustrates dosage-dependent enhancement, with a notable 99 % efficiency achieved at 0.2 wt% MCM-41/UiO-66. Elevated temperatures positively influence demulsification efficiency. The proposed desulfurization mechanism positions MCM-41/UiO-66 as a promising material for broader applications. Recycling tests underscore its excellent reusability and effective recovery, solidifying MCM-41/UiO-66 as a versatile and sustainable solution for petroleum industry challenges.
